Shelby press secretary Jonathan Graffeo says a package arrived in the reception area late Wednesday morning. He says Capitol Police removed the item and are investigating, but no one was hurt.

Graffeo says workers didn't evacuate the office.

The package was one of three suspicious items Senate Sergeant at Arms Terence Gainer says were dropped off at Senate buildings Wednesday.

Also Wednesday, federal authorities announced that preliminary tests showed evidence of the fatal toxin ricin in two letters, one mailed to the White House and the other to Miss. Republican Sen. Roger Wicker. The FBI says both were dated April 8 and postmarked Memphis, Tenn. Authorities say they have a potential suspect.
